[PATCH v6 3/9] PCI: mediatek: Remove the redundant dev->pm_domain check

From: honghui.zhang
Date: Sun Oct 07 2018 - 23:25:25 EST


From: Honghui Zhang <honghui.zhang@xxxxxxxxxxxx>

It's no needed to check whether device have pm_domain attached before
calling the pm_runtime_XXX interface, remove it.
